The most expensive cosmetic on the
market today can be found at Neiman Marcus, Saks Fifth Avenue. ReVive Intensite
Volumizing Serum is created with keratinocyte growth factor and manufactured by
ReVive. The formula is said to turn over dead skin cells eight times faster than
normal skin. However, not everyone can afford this expensive luxury when only
one small ounce costs $600.00 USD.

Dr. Gregory Brown founder of ReVive stated "I
started making it for my mother and me, then I started giving it to patients,
and then a friend of a friend was head of Neiman Marcus and suggested I started
making it for the store."
